DESCRIPTION

32       The  memchan  package provides a C API for use by third-party extension
33       writers. This is exposed by a Tcl stubs library table to reduce version
34       dependency as is available for Tcl itself.
35

COMMAND

37       Tcl_Channel  Memchan_CreateMemoryChannel  (Tcl_Interp *interp, int ini‐
38       tialSize)
39
40       Tcl_Channel Memchan_CreateFifoChannel (Tcl_Interp *interp)
41
42       void Memchan_CreateFifo2Channel (Tcl_Interp *interp, Tcl_Channel *aPtr,
43       Tcl_Channel *bPtr)
44
45       Tcl_Channel Memchan_CreateNullChannel (Tcl_Interp *interp)
46
47       Tcl_Channel Memchan_CreateZeroChannel (Tcl_Interp *interp)
48
49       Tcl_Channel Memchan_CreateRandomChannel (Tcl_Interp *interp)
50
51       Each  of  these  functions  creates an returns a channel exactly as de‐
52       scribed in the Tcl command pages for each of the memchan commands.  The
53       Tcl commands internally call these functions to create the channels.
54
55       The memchan channel accepts an initialSize argument to permit pre-allo‐
56       cating space for the internal buffer. Normally this may be set to 0.
57
58       The fifo2 API function looks a little different because it must  return
59       two linked channels.
